spirit of the invention.

In describing the invention in detail reference Operation is had to theaccompanying drawings wherein embodiments of the invention areillustrated and The operation ofthe applicants improved form 45 whereinlike characters of reference indicate like of lock is as follows: thestrained or normally i60 -parts throughout the several views and inbowed position Yof spring members 14 14, nor- 'whichzmally act torestrain the stop portion 26 of bolt Figure 1 is a part sectional, partelevational member 23 to impinge onto stop kface 36 of side viewof oneAform of locktaken on line 1 1 housing member 3, as shown, this positionformy .of Fig. 2, and Fig. 2 is a partseetional, partfeleing the closedposition of the lock, the bolt por- 105 vational rear View .of thesametaken. on line 2 2 tion 24 being arranged to enter a striking plateofFig. l, and Figs-3 is a bottom elevational view member 37, secured toa door, or wall Astructure of the same taken on line 3 3 of Fig. 1, andas 38. When it is desir-edto unlock the door, the Fig. 4 is a`reduced'size elevational view of the handle 20 is manually `restrainedto the right to roperating side of the same lock, and Fig. 5 is a lthedotted position shown in Fig. 4, this move- H0 ment acting to rotatespindle 10 whereby the upper end portion 13 of springs 14-14 begin to beoppositely bowed, the movement of the handle to the mid-positionproducing a substantially unstable condition of said springs, whereafterfurther movement of said handle to the right acts to inherently movesaid springs to the opposite bowed position as shown by the dotted linesof Fig. l, said inherent movement acting to cornplete the movement ofsaid handle to the right without manual assistance, said movement beingcomparatively rapid or snap acting whereby the bolt portion 24 israpidly moved to open position and normally restrained to remain in thisposition until the handle is returned to its original position whereuponsaid bolt portion will initially move slowly and thereafter rapidly tothe closed position, thereafter being resiliently restrained to remainin this position. v

Referring to the modied form of lock shown in Figs. 6 and 7, the stud 41secured to angle member 42 is arranged to rotatably support spindle 43having fiat sided portion 44, to which is secured, preferably by weldsas 45--45, the upper end portion 46 of bolt member 47, the lower end 48thereof supporting bolt 49 arranged to travel in opening 49a.

Studs 50-50 rigidly secured to bolt member 47 are also rigidly securedto the upper end of spring member 51, the lower end thereof beingpreferably formed into a loop 52 arranged to rotate on stud 53 rigidlysecured to angle housing member 42.

Spindle 43 is also formed with reduced size portion 19 arranged toreceive operating handle 20, the washers 16a-16a acting to compensatefor variation in the thickness of the wall structure to which lock 40 isattached.

The operation of lock 40 is similar to that described in connection withlock 1.

Referring to the modified form of lock shown in Figs. 8 and 9, the boltguide member 6l secured to angle housing member 62 preferably by weldsas 63-63 is arranged to guide the movement of the rear end 64 of boltsupporting member 65 having bolt 56 secured thereto.

Stud 67, rigidly secured to bolt supporting member 65 is arrangedto'guide the movement of the lower end portion 68 of bolt operatingmember 69, said end portion moving between said stud and the angledportion 70 of bolt supporting member 65.

As the handle 20 is moved from one position to the other, the boltmember 71 is moved from right to left or left to right in a horizontalplane whereas the operating portion 68 of bolt operating member 69 ismoved through an arc of a circle between stud 67 and angle portion 70.The operation of lock 60 includes the snap acting characteristicsdescribed in connection with the lock 1.

It is to be noted that by the novel arrangement of the resilient membersas 14 and 51 in substantially a vertical plane, or longitudinally of thelong dimension of the lock housings, the mechanism of the locks areconfined to a comparatively small space transversely thereof, producinga slender appearing or ornate form of locks.

Whereas the angle members 3 and 42 and plate members 4 and 54 comprisingthe housing for the lock mechanism are shown as a separated housing tobe attached to a building structure, said housing may form the integralportion of a hollow wall or door structure of sheet metal and thevarious parts of the lock mechanism inserted therein as the wallstructure is initially formed, thereby further reducing the cost ofvsaid locks as well as eliminating the cost of their attachment duringthe erection of the building.

What I claim isz- 1.
